GEORGE F.,GOODELL, OF MORRISON, ILLINOIS, ASSIGNOR OF ONE-THIRD TO OHAS. BENT, OF SAME PLAGE.

CALENDAR.

SPECIFICATION forming part of Letters Patent No. 255,078, dated March 14, 1882.

Application filed February 19, 1881.

.To all whom it may concern Be it known that I, GEORGE F. GooDELL, of Morrison, in the county of Whiteside and State of Illinois, have invented a new and useful Improvement in Calendars, of which the following is a specification.

The object of my invention is to furnish a calendar adapted for continuous use for indicating days and months, and also for finding the day ofthe week and months of years past,

present, and future.

My invention consists in the combination ot changeable week and month rollers and a calendar-card having upon it a monthly calendar and a key-calendar for use in setting the rollers, all as hereinafter described and claimed.

In the accompanying drawings, Figure l is a face view of my calendar, and Fig. 2 is a cross-section on line .r .e of Fig. 1.

Similar letters of reference indicate corresponding parts.

A is the calendar-card, which may be of any suitable size and shape, and made of card-board or other suitable material.

B is a frame in which the card is iitted.

a b are rollers fitted in hearings c at the back offrame A, and having their spindles extended at one side of the frame for convenient operation. The roller a is the month-roller, and has the names ofthe months printed or affixed on its surface. Roller b has the names of the days ofthe week upon it, arranged in seven linesthat is to say, each line lengthwise ofthe roller has the days of the week in order from left to right, but each line commences with a different day.

In the ard A is an aperture, d, through which tbc month-names on roller a are seen, and also an aperture, e, in front of roller l), for showing the days ofthe week. There is printed on the card,beneath aperture e, a monthly calendar,f. It will be understood that, the day ofthe week on which any month commences being known, it is only necessary to turn roller b until thatday appears `at the left, when the calendar will be set for that'month.

For use in finding the day cf the week on (Model.)

which any lnonth of any year commences, the calendar-card has a key printed upon it, as follows: At g are twelve columns, formed by vertical lines, and containing the names ot' the months at the top. Below the month-names the days ofthe week are placed in order from the top down ward; but they are not in regular order horizontally, such arrangement being according to the years placed at the left on the horizontal lines. These are the common years backward and forward to any extent desired. A similar key is arranged below for the leapyears. t

In using the key the year is tirst found; then by following out that line tothe columns g the day of the week on which each month of that year commences is shown. Thus 1881 is shown in the lower horizontal line, and following that line to the right it is found that January com mences on Saturday, February on Tuesday, and soon. This information being obtained, the roller b can then be set for that month,and the operator .thus obtains a calendar for any month of any year contained in the key. By this arrangement the calendar ,is adapted for ordinary use as a calendar continuously, and at the same time is rendered useful for answering many questions that arise in regard to dates past and future.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patent- As a new article of manufacture,the perpetual calendar, having printed on its face the names of the week and month columns y, the com mon-year columns arranged in the relation thereto as specitied,the leap-year columns,the days-ofthe-week and daysoftl1emonth columnstherefor, the monthly calendarf, theday'sof-the-week and days-of-the-month rollers, all combined and arranged substantially as specitied.
